摘要

阐述了汽车发动机铝合金缸盖罩浇注系统设计、模具设计与制作工艺

介绍了设定的压铸工艺参数:慢压射速度为0.5m/s;快压射速度为4.5

.0m/s;保压时间为10s;压射料质量为4.5kg;压射温度为（650±10）℃;模具温度为180

50℃。针对产品厚大部位的气孔问题

提出了改进工艺措施

并利用铸造模拟软件AnyCasting

对改进后的压铸过程进行了模拟

模拟结果与生产完全一致。生产出来的缸盖罩满足了技术要求

产品的合格率达到98%。

Abstract

Design of gating system and mould for aluminum alloy cam cover of automobile engine was described. The processing parameters are as follows: slow injection velocity of 0.5 m/s

fast injection velocity of 4.5

.0 m/s

holding pressure for 10 s

injection temperature at about 650 ℃ and pre-heated temperature of mould of 180

50 ℃ as well as weight of injected liquid aluminum alloy of 4.5 kg. Aiming at gas hole existed in thick-large location of the casting

improvement of die casting process was performed. Meanwhile

the Anycasting software was employed to simulate filling process in improved die casting design

which is well in agreement with practical production. The cam cover meet the technical requirements and the qualified rate reachs 98%.
